一、前言坑内矿山使用杆柱支护的目的,最初是为了在掘进开拓巷道和矿块回采的准备巷道或采场内的必要之处,提供顶盘区段支护,使在衬砌永久支护之前的一定时间内支撑岩层。因而对坑内装载点、竖井壁、永久峒室及井底车场等还没有发展到采用杆柱。主要是对用作永久支护的杆柱,需要进行进一步的研究与处理;但现在国内外,尤其国外对杆柱的研究探索结果,认为用杆柱支护可作为永久支护使用。 I. INTRODUCTION The purpose of the pillars used in the pits in the pit was initially provided for the necessary support of the roadways or stopes in the tunneling and mining of the roadways and the recovery of the nuggets, Before supporting a certain period of rock formation. Thus on the pit loading point, shaft wall, permanent 峒 room and bottom of the yard has not been developed to use the pole. Mainly for the permanent support of the pole, need further research and treatment; but now at home and abroad, especially abroad to explore the results of the pole, that the use of pole support can be used as a permanent support.
